Hi!
No! A CUB is not the way to go if you want to start R/C flying!
The reason is simple: There are far better flying airplanes to choose from than a CUB.

If you don't buy the above fact...then here comes some more....
The CUB has very brittle wing fastening system with its large windows that will instantly brake as soon as you crash the first time.
It is also a taildragger and as such is not as easy to steer at take off as a nose wheeled airplane. Believe me.... newcomers do have difficulties just steering an airplane when it accelerates on take off. Most people being right handed have difficulties steering with their left hand.
The CUB also has a straight wing which means it is not as forgiving in flight compared to a normal high winged trainer.
There you are!
I can't understand why somebody would choose a harder way to get started in this wonderful hobby than is needed.
Why invent the wheel again??
High winged trainers are there for just one purpose...to learn people how to fly! They are not beautiful...but they serve a purpose....
After you have learned to fly (on a trainer aircraft getting help from a club...other vise it is nearly useless you try) then you can build, buy, get a more beautiful airplane.
